I think you mean use the object before it is defined. This would probably mean 
a two-pass evaluation of the source file.  While two passes are necessary for 
e.g., TOC and index I don't see the necessity of using objects first, 
defining them later.  TeX is essentially a linear process, front to back.

IMHO of course.
